Behind every great athlete is a boss or coach who pushed them as hard as possible. In NASCAR, very few driver and owner teams were as famous or successful as Mark Martin and Jack Roush. During his great Hall of Fame career, Martin won 40 NASCAR Cup Series races between 1989 and 2009. An amazing 35 of those wins came while driving a Ford for Roush Racing. But looking past all the trophies and victory photos, the two men had a very tough, complicated relationship behind closed doors.

Recently, Martin went on the Dale Jr. Download podcast. He told a shocking story about his old boss. Back in 1989, Jack Roush got in big trouble with the police. Roush was flying his own plane and decided to land it right on a test track in Ohio. He did this without asking for permission first. But rather than feeling sympathy, the NASCAR Hall of Famer admitted he was actually glad to see his longtime team owner held accountable.

Martin did not say this because he hated Roush. He said it because the 1989 plane story reminded him of how strict Roush was in the early days of their team. Working for Roush was incredibly hard. To prove how high the pressure was, Martin shared a story about how Roush made him break down in tears before their very first race together.

“He made me cry ball before we ever went to our first race. Because I was going to drive the Bill Davis Busch car down there, too. And he, you know, you used to smash exhaust pipes down underneath the frame rails. Well, he was smart enough because he’s smarter than all the rest of us down here to cone the tail pipes so that when they were smashed, they still flowed the same. So, you had to take a bigger pipe than your 3-and-a-half-inch or 3-inch, you know, and smash it down. So, I saw that. So, I went over to Bill Davis and built a set for the Busch car because it seemed like smart. And he found out about it.” Mark Martin said on the podcast.

Mark Martin explained that he had joined the newly formed Roush Racing organization in 1988 in the Winston Cup Series while also competing in the Busch Series for Bill Davis.

Roush had created a very smart design for the exhaust pipes on his cars. In racing, the metal pipes under the car often hit the ground and get smashed flat against the race track. Roush figured out how to shape the inside of the pipes like a cone.

This meant that even when the metal got flattened, the air still flowed out perfectly. This gave the car maximum speed. Martin thought this was just smart, normal building.

So, he recreated it on the Busch car, believing it was simply smart engineering. He never considered that Roush would view it as giving away one of his team’s competitive secrets.

When Roush discovered what had happened, he exploded. The veteran owner believed Mark Martin had shared proprietary knowledge with another organization and let the young driver know exactly how he felt.

The confrontation devastated Martin, who admitted he “cried like a baby” because all he wanted was Roush’s approval.

At that stage of his career, Martin felt he owed everything to Roush. Before 1988, no other big team owner was willing to give Martin a real chance in the top Cup Series. Roush was the only man who believed in him enough to give him a ride. That is why he felt indebted to the veteran team owner. This is why Martin has opened up about the incident now, years after his retirement.

Despite the rocky beginning, the relationship ultimately flourished. Mark Martin’s first season with Roush Racing produced three top-five and 10 top-10 finishes before the partnership blossomed into one of NASCAR’s greatest success stories.

Together, they won 35 Cup races, proving that while the lessons were often harsh, they helped build a Hall of Fame career.
